The mixed-valence trinuclear cobalt compound {[Co(CN)(3)((BuNC)-Bu-t)(2)](mu-CN)[Co((BuNC)-Bu-t)(4)](mu-CN)[Co(CN)(3)-((BuNC)-Bu-t)(2)]} is produced from the reaction of CoCl2 with KCN and tert-butylisocyanide. In the resulting structure two cobalt atoms formally show the oxidation state +III, whereas the central cobalt still exhibits the formal oxidation state +II All cobalt atoms are octahedrally coordinated by cyanide and isocyanide ligands. The supramolecular structure is determined by C-...The mixed-valence trinuclear cobalt compound {[Co(CN)(3)((BuNC)-Bu-t)(2)](mu-CN)[Co((BuNC)-Bu-t)(4)](mu-CN)[Co(CN)(3)-((BuNC)-Bu-t)(2)]} is produced from the reaction of CoCl2 with KCN and tert-butylisocyanide.
